What are the AI technologies currently used to fight the coronavirus pandemic?
According to the Baidu Research's blog post How Baidu is harnessing the power of AI in the battle against coronavirus (12-03-2020), there are already some artificial intelligence tools or algorithms being used to fight the coronavirus.
Given that I cannot confirm that these AI tools and algorithms I will mention are really being used in practice, I will only quote the parts of the blog post that potentially answer my original question.
To give some context, similar to HIV viruses, the virus that is causing the coronavirus pandemic, SARS-CoV-2 is capable of rapidly mutating, making vaccine development and virus analysis difficult.
AI-powered and non-contact infrared sensor system

Baidu has developed several tools that are effective in building awareness and screening populations, including an AI-powered, non-contact infrared sensor system that provides users with fast multi-person temperature monitoring that can quickly detect a person if they are suspected of having a fever, one of the many symptoms of the coronavirus. This technology is currently being used in Beijing's Qinghe Railway Station to identify passengers who are potentially infected where it can examine up to 200 people in one minute without disrupting passenger flow.

AI-powered pneumonia screening and lesion detection system

By leveraging PaddlePaddle and the semantic segmentation toolkit PaddleSeg, LinkingMed has developed an AI-powered pneumonia screening and lesion detection system, putting it into use in the hospital affiliated with XiangNan University in Hunan Province. The system can pinpoint the disease in less than one minute, with a detection accuracy of 92% and a recall rate of 97% on test data sets.

Automated HealthMap system

The Boston Children's Hospital used an automated HealthMap system that scans online news and social media reports for early warning signs of outbreaks, which led to the initial awareness that COVID-19 was spreading outside China.

Autonomous vehicles carry out non-contact tasks

Access to health care and resources at a moment's notice is vital for battling the spread of the coronavirus. Autonomous vehicles are playing a useful role in providing access to necessary commodities for health-care professionals and the public alike by delivering goods in infected areas and disinfecting hospitals, effectively minimizing person-to-person transmission and alleviating the shortage of medical staff.
Apollo, Baidu's autonomous vehicle platform, partnered with a local self-driving startup called Neolix to deliver supplies and food to the Beijing Haidian Hospital.
